Final Design

The Final Design (FD) Phase formally begins once Federal Highway Administration (FHWA) approves the FD funding and the FD Addendum is executed. If the Preliminary Engineering (PE) Designer is not retained for FD, the process to select a new designer is initiated. This phase of project development concludes in the completion of construction contract documents (i.e., project plans, specifications, construction schedule and construction estimate).

The FD Phase includes continuing and completing tasks started during the PE Phase, such as roadway design, bridge design, right of way and access engineering, utility engineering, environmental permits and clearances, risk management and community outreach. The completion of these tasks involves various internal and external project stakeholders. Stakeholder coordination includes review meetings with internal offices and communication with local officials, the general public and other state and federal agencies. Communication with public and local officials is guided by a project-specific public involvement action plan.

Note: Projects meeting the requirements of Limited Scope will include a subset of the FD Phase elements listed above.

The FD Phase is completed when the project is authorized for construction, which initiates the Construction (CON) Phase of project delivery. FD closeout activities include closing the project’s design job number and issuing an addendum to the design consultant’s contract covering any needed construction engineering services.

Objective(s)

The major objective of the FD Phase is to produce the project’s construction contract documents (i.e., Final Plans, Specifications, and Cost Estimate) for use in soliciting bids from prospective contractors, and moving the project to the CON Phase. This requires the continuation and completion of environmental and engineering tasks initiated in the PE Phase.

An important objective during the FD Phase is to maintain the project’s scope, as defined by the products completed during the Concept Development (CD) and PE Phases. Some actions used to maintain the project’s scope include informing stakeholders of the project’s scope, the main goals and objectives and schedule and budgetary constraints. Any proposed change in the project scope, as defined in the New Jersey Department of Transportation's (NJDOT) project development procedures, requires approval from NJDOT’s Change Control Board.

Developing quality products is another important objective of the FD Phase. The phase includes quality-based tasks, such as completion of the Quality Management Final Design Submission Certification and Plans, Specifications and Estimate Certification by the designer, the completion of a formal Design Communications Report (DCR) for each project, and the use of on-board reviews to obtain any necessary input and guidance from various subject matter experts.  The DCR documents the various coordination efforts completed for the project with internal and external stakeholders, and serves to document project-related directions and decisions.

Maintenance of the project’s budget and schedule are also important objectives of the FD Phase. The phase includes budget and schedule maintenance tasks, including routine monitoring and updating of the budget and schedule, maintenance of the project’s scope, and identifying and approving budget and/or schedule revisions when necessary.

Funding

Funding for the FD Phase requires authorization and may involve state and/or federal funding sources. Depending on the project’s specific scope, funding authorizations also may be needed for the purchase of right of way, and for utility accommodations associated with the CON Phase. When using federal funding, authorization requests must be supported by an environmental document.

Key Stakeholders

Producing the project’s construction contract documents and obtaining the necessary environmental permits and clearances requires coordination with numerous internal and external stakeholders.  Major internal stakeholders include Subject Matter Experts (SME) in design, environmental, and landscape architecture offices, and NJDOT’s administrative management and public relations personnel. Additional outside agencies include other state and federal transportation agencies, state and federal environmental resource agencies, and offices and organizations affiliated with any counties and municipalities affected by the project. 

During this phase, the FD Public Involvement Action Plan (PIAP) is executed for the project, that will guide activities to communicate news and information to municipal, county and state officials and the general public. Specific activities will vary depending on the project’s scope and complexity. Actions may include public information centers, formal public hearings, briefings with municipal, county and state representatives, press releases, a project-specific web site, and newsletters.
